When you deploy code from a repo, class (file) deletion might not be reflected by your CICD system.
Here's a simple one-liner to automatically delete all classes in a specified package that have not been imported. It can be easily adjusted for a variety of adjunct tasks:

set packages = "USER.*,MyCustomPackage.*"
set dir = "C:\InterSystems\src\"
set sc = $SYSTEM.OBJ.LoadDir(dir,"ck", .err, 1, .loaded)
set sc = $SYSTEM.OBJ.Delete(packages _ ",'" _ $LTS($LI($LFS(loaded_",",".cls,"), 1, *-1), ",'"),, .err2)

The first command compiles classes and also returns a list of loaded classes. The second command deletes all classes from specified packages, except for the classes loaded just before that.

I'm trying to setup a REST server with CORS support. I have created a class that handles a specific part of the service (printer control). This class I have referenced in my main REST class by adding <Map Prefix="/print" Forward="myClass.PrintAPI" />

My main class does have its own <Route>s and handles CORS requests perfectly. But in my subclass OnHandleCorsRequest() is only run when requesting from same origin and never run when making a CORS request. I have set Parameter HandleCorsRequest = "true" in both my main REST class and the subclass.

Hey Developers,

HI,

I am planning to build a WebApp that will have tons of data to display in tables, ability to add comments on that table rows and may be some few more small features as we move on.

1. It has to be Secure

2. It has to be fast

3. It has to be Non CSP / Non Zen

4. Will have Cache DB to pull records from but should be flexible to do that from any odbc resource

5. Version 2018 Ensemble

My first step would have been to investigate different options for technologies that would make it work and best suited with Ensemble 2018

In a Business Process using the %PrimaryRequestHeader I can call GetAdapterSettingValue and get the setting from a Business Service. But once I am in the Business Operation there is no class for %PrimaryRequestHeader. Is there another way to get setting in the Business Operation that was define in the Business Service ?​

Hi everyone,

I've created an Identicon Generator inspired on Fabio Gonçalves Captcha Validator.

This sample can be used to create Identicons for users of app for example, it can be useful to use in Zen Mojo applications, generating an identifier image based on name of the user by example, but it can be used in others kind of applications too(Zen, CSP etc)

Hello,

Is there a install kit available for ubuntu. I have tried the Suse Install kit .

Got: The installer can't find a platform in this distribution supported by your system

Hi Developers,

We are happy to announce the new InterSystems online programming contest dedicated to all things health-related:

🏆 InterSystems FHIR and Digital Health Interoperability Contest 🏆

Duration: May 12 - June 1, 2025

Prize pool: $12,000

Welcome, dear members of the community!

In this article we are going to demonstrate the great potential that IRIS/HealthConnect makes available to all its users with the use of Embedded Python and we are going to do it by developing a small production that will allow us to recognize and identify the faces present in a JPG file from some images that we will use as a reference.

We're upgrading to IRIS 2020.1 from Ensemble 2018.x.

I have a lookup table class that compiles fine in Ensemble but in IRIS causes the following compilation error: "ERROR #9101: Global name 'HH.LookupLabResultsToPhysiciansD' for 'IDLocation' is too long, must be no more than 31 characters in length."

Is this length limitation a new restriction or could I have done something years ago to increase the maximum character length.

Thanks,

Jim

Running predictive models natively in an InterSystems IRIS Business Process has of course always been the goal of our PMML support, but somehow never made it into the kit because there were a few dependencies and choices that needed addressing and answering. Anyhow, thanks to some pushing and code kindly provided by @Amir Samary (Thanks again Amir!), we finally got it wrapped in a GitHub repo for your enjoyment, review and suggestions.

Suppose you have an application that allows users to write posts and comment on them. (Wait... that sounds familiar...)

For a given user, you want to be able to list all of the published posts with which that user has interacted - that is, either authored or commented on. How do you make this as fast as possible?

Here's what our %Persistent class definitions might look like as a starting point (storage definitions are important, but omitted for brevity):

Using VSCode in a team.

Classes are edited locally and then saved to server.

Sometimes if we save a change to a class the "version on the server" does not happen or does not function properly and the class gets overwritten.

All the intersystems extensions are updated.

objectscript.overwriteServerChanges is false

This has the potential for serious issues if it happens in a persistent class, but it is difficult to reliably recreate.
